3.9 X feeder modules for SIPLACE SX1/SX2
The SIPLACE SX1/SX2 uses the entire spectrum of the SIPLACE X feeder modules. All SIPLACE
X feeder modules are compatible with the changeover tables of the SIPLACE SX1/SX2 and can
be used without restrictions. Key properties of the SIPLACE X feeder modules include the high
precision of the pickup position, online programmability, status displays on an LCD display and
simple handling for feeder module changes during the placement process. The power supply to
the feeder modules is contactless and uses an inductive interface. Each feeder module commu-
nicates with the feeder module control unit (FCU) via two optoelectronic channels (optical fiber).
The two interfaces form the EDIF assembly (energy and data interface, see item 2 in fig. 3.9 - 1
,
page 146
). The feeder module control unit is connected to the control unit of the machine via the
CAN bus.
3.9.1 Tape feeder modules for the SIPLACE X-Series
3.9.1.1 Tape material
The possible tape widths range from 4 mm to 88 mm. The tape material is blister or paper. Com-
ponent tapes with a permanently adhesive cover foil (PSA foil) can also be processed. This will
require the "PSA Kit" option.
The design of the tape feeder modules was based on the following tape standards:
DIN EN 60286-3 (12/1998) / IEC 60286-3 (12/1997)
JIS C 0806-3 (1999)
ANSI/EIA 481-C (10/2003)
IEC 60286-3-2 3
PSA Kit Item no.
8 mm X PSA Kit 00141224-xx
12 mm X PSA Kit 00141225-xx
16 mm X PSA Kit 00141227-xx

The overall height of the blister tapes depends on the tape width, and must not exceed the follow-
ing maximum values:
For 8 mm paper tapes, the paper thickness must not exceed 1.6 mm. The length of a component
pocket in the direction of tape travel may not exceed 51 mm.
3.9.1.2 Tape reel diameter
The tape reel diameter may be up to 19" (483 mm) for all feeder modules. For a list of the maxi-
mum tape reel diameters, in accordance with the PCB conveyor height, refer to section 3.10.7.2
,
page 181
.
3.9.1.3 Manual removal of tantalum capacitors that were not picked up by theoperator
To prevent tantalum capacitors which were not picked up from causing the tape material to burn
when it is cut, the user interface has been extended to include the option "Stop immediately on
pickup error". This option must be enabled in SIPLACE Pro. On the placement machine, the com-
ponent that was not picked up is paced forward again until it is ready for removal from the com-
ponent tape. The track is deactivated and the operator is sent an error message to remind him to
pick up the tantalum component from the tape. If an alternative track is available, the machine con-
tinues placing. The operator is able to stop the machine, however, and pick up the tantalum com-
ponent. If no alternative track is available and it is not possible to continue placement with other
components, the machine will stop. At this point, the operator can again remove the tantalum com-
ponent and acknowledge the error. Once the operator has restarted the machine, placement is
continued and components are picked up from the track that is now enabled once more.

PLEASE NOTE
This software function is also a good idea for expensive components.
Please observe the safety instructions for capacitors on metallic powder basis (see
section 2.5.3
, page 57).
